Publication Non-Invasive assessment of short and ultra-short heart rate variability during different physical and physiological tests(Univ Zagreb, Fac Kinesiology, 2021-06-01) Alparslan, Tuncay; Arabacı, Ramiz; Görgülü, Recep; ARABACI, RAMİZ; GÖRGÜLÜ, RECEP; Bursa Uludağ Üniversitesi/Spor Bilimleri Fakültesi; 0000-0001-8403-5742; 0000-0003-2590-4893; ABI-4831-2020; N-8905-2015The main aim of the present study was to determine the short- and ultra-short-term heart rate variability (HRV) during different physical and physiological tests and to compare HRV to different performance levels. The latter aim was to compare participants' short- and ultra-short-term heart rate variability before-, during-, and post-tests. Our hypothesis was that there would be a significant difference between test performance and HRV parameters, and the high performing group would have significantly higher HRV parameters than the low performing group. Fifty-three healthy men (Mage=26.9 +/- 4 years, Mheight=177.9 +/- 5.7 cm; Mweight=77.8 +/- 8.7 kg) were recruited in the current study. We completed the data collection procedure for each participant in four consecutive days. On day-1, anthropometric measurements were conducted and then participants performed isokinetic tests. On day-2, participants performed anaerobic tests; on day-3 equilibrium tests, and on day-4 aerobic capacity tests. The HRV records of all participants were obtained before, during and after all these tests. Based on the participants' performance, they were classified into two groups: participants in G1 had lower performance and those in G2 higher performance. A two-way repeated measures ANOVA yielded significant differences in HRV values obtained in the four different tests. There was a significant difference between fitness test performance groups in the variation of short- and ultra-short-term HRV parameters.Publication Effects of intermittent hypdxic training on normoxic exercise performance in elite wrestlers(Scibulcom, 2015-01-01) Arabacı, Ramiz; ARABACI, RAMİZ; Uludağ Üniversitesi/Spor Bilimleri; 0000-0001-8403-5742; ABI-4831-2020The aim of present study was to assess the effect of intermittent hypoxic training (IHT) on anaerobic power, aerobic capacity and dynamic muscular maximum strength (1-RM) in elite freestyle wrestlers. Thirty elite freestyle wrestlers (mean age 23.4 +/- 4.1 years; height 169.1 +/- 15.4 cm; body mass 74.2 1 +/- 10.4 kg) who competed in Turkish First Wrestling League voluntary participated in present study. A pre-post randomised controlled training intervention design was employed to analyse the effect of an IHT program on anaerobic power, aerobic capacity and dynamic muscular maximum strength. Subjects were randomly divided into two groups: the first group performed normal usual normoxic wrestling training ( sea level) during a 8-week period (CG), while the second group performed usual normoxic wrestling training plus an IHT program (twice a week) in similar to 2000 m altitude during a 8-week period (IHTG).In conclusion, the use twice a week of intermittent hypoxic training increased anaerobic power, 1-RM and aerobic capacity of elite freestyle wrestlers.Publication Fluid consumption habits of elite athletes(Scibulcom, 2015-01-01) Arabacı, R.; ARABACI, RAMİZ; Bursa Uludağ Üniversitesi/Spor Bilimleri Fakültesi/Beden Eğitimi ve Spor Bölümü.; 0000-0001-8403-5742; ABI-4831-2020The objective of present study was to examine fluid consumption habits of elite Turkish athletes and compared total fluid intake of training (TD) and non-training (NTD) days. A total of 142 male and 103 female Turkish elite athlete volunteers participated in present study. Written questions asked techniques were used for data collection. Questionnaire collected personal knowledge and assessed fluid consumption of subjects. To compared NTD and TD fluid consumption was used independent samples t-test.Female athletes in NTD and TD intake water 1066.4 ml/day (47.5%) and 1518.4 ml/day (51.4%), tea 386.1 ml/day (17.2%) and 534.7 ml/day (18.1%), fruit juice 175.1 ml/day (7.8%) and 239.3 ml/day (8.1%), energy drinks 40.4 ml/day (1.8%) and 85.7 ml/day (2.9%), respectively. Male athletes in NTD and TD intake water 1192.1 ml/day (48.4%) and 1653.7 ml/day (52.1%), tea 445.8 ml/day (18.1%) and 568.1 ml/day (17.9%), fruit juice 169.9 ml/day (6.9%) and 241.2 ml/day (7.6%), energy drinks 54.2 ml/day (2.2%) and 98.4 ml/day (3.1%), respectively. Male subjects consumed 28.9% more fluid in TD (3174 +/- 46.3) than NTD (2463 +/- 32.1 ml/day). Female subjects consumed 31.6% more fluid in TD (2954 +/- 35.4) than NTD (2245 +/- 45.2 ml/day).Adequate fluid consumption, especially water intake is very important for athletes. Athletes have been increased fluid intake in training days. Water is the most increased fluid. This may be related to excessive sweating of athletes during exercise.Publication Acute effects of static stretching on peak and end-range hamstring-to-quadriceps functional ratios(Baishideng Publishing Group Inc, 2015-10-18) Şekir, Ufuk; Arabacı, Ramiz; Akova, Bedrettin; ŞEKİR, UFUK; ARABACI, RAMİZ; AKOVA, BEDRETTİN; Uludağ Üniversitesi/Tıp Fakültesi/Spor Hekimliği Anabilim Dalı; Uludağ Üniversitesi/Spor Bilimleri Fakültesi/Beden Eğitimi ve Spor Bölümü; 0000-0003-2735-8697; 0000-0003-1044-8805; R-5044-2018; ABI-4831-2020; AAI-4550-2021; AAM-4348-2020AIM: To evaluate if static stretching influences peak and end-range functional hamstring-to-quadriceps (H/Q) strength ratios in elite women athletes.METHODS: Eleven healthy female athletes in an elite competitive level participated to the study. All the participants fulfilled the static stretching or non-stretching (control) intervention protocol in a randomized design on different days. Two static unassisted stretching exercises, one in standing and one in sitting position, were used to stretch both the hamstring and quadriceps muscles during these protocols. The total time for the static stretching was 6 +/- 1 min. The isokinetic peak torque measurements for the hamstring and quadriceps muscles in eccentric and concentric modes and the calculations for the functional H/Q strength ratios at angular velocities of 60 degrees/s and 180 degrees/s were made before (pre) and after (post) the control or stretching intervention. The strength measurements and functional strength ratio calculations were based during the entire-and end-range of knee extension.RESULTS: The pre-test scores for quadriceps and hamstring peak torque and end range values were not significantly different between the groups (P > 0.05). Subsequently, although the control group did not exhibit significant changes in quadriceps and hamstring muscle strength (P > 0.05), static stretching decreased eccentric and concentric quadriceps muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). Similarly, static stretching also decreased eccentric and concentric hamstring muscle strength at both the 60 degrees/s and 180 degrees/s test speeds (P < 0.01). On the other hand, when the functional H/Q strength ratios were taken into consideration, the pre-intervention values were not significant different between the groups both during the entire and end range of knee extension (P > 0.05). Furthermore, the functional H/Q strength ratios exhibited no significant alterations during the entire and end ranges of knee extension both in the static stretching or the control intervention (P > 0.05).CONCLUSION: According to our results, static stretching routine does not influence functional H/Q ratio. Athletes can confidently perform static stretching during their warm-up routines.
